Vacant lot circles - no kidding

The 13 foot diameter circle showed up on or about Aug 12, 2003. The leaves and stems of the grasses in the circle are gently laid over starting from the center of the circle, and pointing out towards the outer edges of the circle as spokes on a wheel. There are no obvious breaks or bends in the stems. All seem to have laid down as if they were wilted, although the plants do seem to be alive and healthy. The leaves and stems have not yet made any discernable movement towards straightening back out.
